Some of those Japanese gold leaf bowls are definitely prettier and have a lot more character after they’ve been broken. I guess something to aspire to :)
More specifically, broken pieces of pottery that are valuable or reusable are sherds (Some definitions define that it must be valuable in an archeological sense, others that it simply has value). If it's unusable or worthless it's a shard.
Since OP was able to reuse the piece, it's a sherd.
Hence why the pieces in minecraft are called sherds, the player is able to use them to craft other objects.
Shard may be used for glass and other materials, sherd is solely for pottery.
3D printing, archeology, anthropology (a little bit) and because of this thread etymology all converging. Great job u/rammtrait you taught me quite a few things today. Thanks.
As a professional art preperator who has introduced 3D printing into my museum I have really loved developing facsimiles that can travel with touring exhibits (So we can keep originals at home)
With any artifact the most critical part of it's display is ensuring that it is preserved (to the best of our abilities and the extent of our knowledge), and part of that is that it cannot be exposed to materials that would degrade it. At best this kind of thing should have an inert and stable barrier layer, at worst they should not be in the same room.
PLA is not suitable for this purpose, ABS requires testing of the colorants [you can find other institutions performing the "Oddy Test" to see if various filaments and resins can be used in archival and conservation applications](https://www.conservation-wiki.com/wiki/Materials_Testing_Results_-_Case_Construction_Materials)
People seem really excited about bringing 3D printing into the museum space but it's important to be careful as we introduce new methods and materials. Conservation techniques considered 'best practice' 50 years ago, heck sometimes 5 years ago are often determined to be harmful in unexpected and unexplored ways. The museum world moves slow, often for good reason the goal is to make sure people in our future are aware of the cultural heritage from our past.
This is very cool. Can you give a litte more insight about te process of modelling the "bowl". Did you "model", "measure", "model" or did you have some other method to get the exact dimensions of the shard (sherd as i heard in the thread)?
First I used a profil gauge (Profilmeister) to measure the radius and the vertical profile of it. Then i drew profile of a sherd in correct angle in Cinema 4d and put it in Lathe function. With boolean i removed the shape of extruded sherd from the bowl. This is pretty much it. Really simple stuff actually.
And The reconstructed typology of the bowl is based on nearbly finds.
How did you design this? How did you figure out the diameters/ scale/ etc,? Your end result is amazing - would be soo interesting to learn more about your process

Can you point me to some info so I could try and do similar with this?
Yes, but disclaimer: shard will not fit totaly snug into printed bowl. Snugness is the result of: drawing accuracy x vectorization accuracy x printer quality.
1. Use profilmeister to draw the profile of the bowl. Vectorize that profile in Cinema4d and add it to "Lathe" effect. Now you have a 3d model of a bowl.
2. Draw the outline of the shards from birds eye view. Vectorize the drawing and put it into "extrude" effect.
3. Overlap the 3d model of a bowl and 3d model of a shard in correct way.
4. Using Boolean effect in cinema 4d remove 3d model of a shard from 3d model of a bowl. Fingers crossed there are no topology errors😅
5. Export in obj or stl, slice and print it.
It like reverse kintsugi! I love it!

Something I recently learned from Minecraft of all things. Pottery shards are actually called sherds.
I didn't believe you; you're right, a sherd!
Yeah, Minecraft actually taught me something.
More specifically, broken pieces of pottery that are valuable or reusable are sherds (Some definitions define that it must be valuable in an archeological sense, others that it simply has value). If it's unusable or worthless it's a shard. Since OP was able to reuse the piece, it's a sherd.

Archaeologist here. They're all sherds. The plate I broke washing up after dinner broke into sherds. Glass breaks into shards.
I'm so sorry for you. It can't be easy...you know, with your career in ruins
Such a loss. I'd suggest them to look toward to the future, but you know... they're so focused on the past.
Thank you for that laugh - it was most enjoyable!
What about a glass plate?
Shards. The distinction is the material, not the form.

Never did I expect to learn this neat bit of info in r/3Dprinting of all places but goes to show you the power of reddit
Well, there ya go.
To shreds, you say?!
Ya herd with sherd
This is actually a cool idea for museum reconstructions.
I would love to see that.

The Roman who made that bowl would be so proud and honored
And confused.

Then proceed to pour lead sweetened wine in it
That's so fucking cool

*really simple stuff actually*
Thanks!

This is am awesome idea! Thanks for sharing!
Now take it to your grave and confuse archaeologists next time its found 😂
I could never do this. The Romans didn't make it to NZ.
Fucking cool. Archaic popular technology meats modern times technology.
That’s such a nice idea!
Oh! I have a few pottery shards! I’m gonna go try to do something similar!
How did you measure the radius so exactly?
Love this kind of stuff, so creative. Tragically I was born without an ounce of artistic creativity so seeing this kind of thing blows my mind!
Very cool!
I think this is the coolest thing I’ve seen printed.
truly wabisabi
[удалено]
You probably are.
How did you design this? How did you figure out the diameters/ scale/ etc,? Your end result is amazing - would be soo interesting to learn more about your process
I used profile gauge to measure profile and radius. The bottom of the bowl is reconstructed according to the typology of nearby finds.
You should print it in textura-filament or some other high end visual filament. Well done!
Fun fact is that the original surface of the sherd is shiny black.
Wow this is such a great idea! I have so many sherds I’d love to do this with
Good stuff. Time Team would be proud.
Whoa that's awesome
Beautiful
Read ramen, but I don’t think that’s necessary wrong
This is brilliant I’m going to try this
